Knee Replacement in Congo – Part I

Posted on August 5, 2016.

by: Kathleen A Hogan, MD

The Democratic Republic of Congo

The Democratic Republic of Congo (DRC), formerly known as Zaire, is not a tourist destination.    Because of ongoing violence, much of the country is inaccessible.   There are warnings for travelers posted on the US Embassy website. There is an ongoing yellow fever epidemic.   The DRC is one of the largest countries in Africa and also one of the poorest.  The country has been devastated by multiple wars, corruption, and a dictatorship. So why would I travel there?    

Knee Replacements at Biamba Marie Mutombo Hospital

I am part of a group of female orthopedic surgeons (WOGO) who travel to third world countries to improve the lives of people by improving mobility through joint replacement.   We also believe it is important to teach doctors in those communities and to be role models for young women. Dikembe Mutombo, an NBA Hall of Fame basketball player, who is from Congo, asked our group to go to his hospital. Biamba Marie Mutombo Hospital is a 150 bed hospital with modern equipment including the only CT scanner in the country, an intensive care unit, and 3 operating rooms. Our group would be performing the first knee replacements done in that hospital, and possibly the first done in the country.  This was an incredibly challenging trip.  This is our story of what it was like to do knee replacements in Congo.

Travel and Logistics

It was a long plane ride.  Over 16 hours of travel.   We were met at the airport by police officers with machine guns who would be traveling with us everywhere we went.   The team was all assembled at the hotel. We are a large group with over 40 volunteers  including surgeons, scrub techs, nurses, anesthesiologists, internists, physical therapists, and a translator. Last month, a smaller team had traveled to Congo for the weekend to select patients for surgery.   We arrived Thursday evening, with the plan to start operating on Friday.   We planned to do  52 knee replacements in 4 days of surgery.  In March, 9000 lbs of orthopedic equipment and supplies had been sent by ship to the DRC.  We had been told the cargo was there and an advance team had arrived  a day early to unload and unpack the shipping container.


There was only one problem.  The cargo was not at the hospital.   It was in the country, but we needed a signature, or maybe more than one, in order for it to be released from customs.   Mr. Mutombo spent Thursday and Friday trying to get those signatures.   Our team was waiting at the hospital to unload the cargo.  By 6pm on Friday, we were worried.  Supposedly the signatures had been obtained but a customs agent could not be found to escort the cargo.  An ultimatum was given.  If the cargo did not arrive by 7 am the next day we would not be able to do our surgeries.   We were about to leave the hospital when word came that the cargo was on its was on its way.  Mr. Mutombo had called the president of the country, and a customs agent had been found.


The shipping container arrived around 9.30 pm, along with Mr. Mutombo.  We were tired, hungry, jet-lagged, and excited.  Everyone pitched in to unload hundreds of boxes and more them to the operating rooms and the hospital floor.  Boxes were loaded onto stretchers and laundry carts.   It was truly a team effort.   Pizza arrived an hour later and was the best pizza we had ever tasted. But boxes still needed to be unpacked and the equipment organized. By midnight we were all on the bus for the ride to the hotel.   The  next day buses would leave at 6.30 am and we would finally be able to start doing knee replacements.

This story will be continued next month.

Top Three Things to Do Before Having Surgery

Posted on July 5, 2016.

by: Kathleen A. Hogan, MD

Everyone who has surgery worries about what can go wrong.   No surgery, no matter how minor, is without some risk.   However there are a few things that you can do before having surgery which may reduce the risk of complications.

Stop Smoking

Yes, smoking can result in lung cancer.   But there are more immediate risks for smokers having surgery.   Studies have shown significantly increased risks of heart attacks, strokes, pneumonia, blood clots, infection, and death after surgery in smokers.   Nicotine also impairs the body’s ability to heal surgical wounds, thereby increasing the risk of infection.  Fractures heal more slowly in smokers and there is a risk that joint replacement implants will not properly adhere to the bone in smokers.   It is recommended to stop smoking at least 6 weeks before your planned surgery.

Lose Weight

No one likes, or needs to be told to lose weight.  However, obesity may increase the risk of surgical complications such as heart attacks and urinary tract infections. The risk of infection after joint replacement rises exponentially in patients who are significantly overweight.   These risks are further increased in patients with high blood pressure, diabetes, or heart disease. How do you know if you are overweight? Calculate your body mass index by dividing your weight (kg) by height squared (cm). In New Hampshire, approximately 36% of adults are overweight (BMI>25) and 26% are obese (BMI>30). Weight loss is not easy, but may decrease your risk of surgical complications.

Visit a Dentist

According to the CDC, more than 20% of adults have untreated cavities.  Studies have shown that improving oral care preoperatively reduces the risk of pneumonia and mortality after cardiac surgery.  Infections around the teeth can spread bacteria into the blood stream and can cause severe infections around total joint replacements.  I ask my patients if they have untreated dental disease and postpone surgery until it is resolved.   Only 61% of adults visited the dentist within the past year.  Brush and floss daily and visit a dentist at least once each year.

Is it more difficult to stop smoking, lose weight, or get a root canal? None of these things are easy or fun to do.  However, they are three steps that should be considered before having elective surgery in order to decrease the risk of complications.  Discuss these issues with your doctor if you are planning on having joint replacement surgery.

36 hours in the Congo

“Going up that river was like traveling back to the earliest beginnings of the world, when vegetation rioted on the earth and the big trees were kings.”
 Joseph Conrad – Heart of Darkness

Traveling to the Democratic Republic of Congo (DRC)

It takes approximately 19 hours, flying over 7000 miles to reach the Democratic Republic of Congo (DRC) from Boston.  It is not a trip that many people take for just a weekend. Indeed, the DRC is not a place frequented by American tourists.   But recently I found myself flying to the Congo for a quick 36 hour trip.  Why?  Together with a nurse, an internist, another orthopedic surgeon and a physician assistant, I was there to pre-screen patients for total knee replacements at the Biamba Marie Mutombo Hospital in Kinshasa.    

Why the DRC?

I am part of a group of female orthopedic surgeons (WOGO) who travel to third world countries to improve the lives of people by improving mobility through joint replacement.   We also believe it is important to teach doctors in those communities and to be role models for young women. On this trip, we are partnering with the Dikembe Mutombo Foundation (DMF).  Dikembe Mutombo, a former all-star professional basketball player, is from Kinshasa and has developed this foundation to improve the health, education, and quality of life of the people of the Congo. The hospital opened in 2007 and is named after his mother. Over 100,000 people have been treated since it opened.

About the DRC

The DRC is located in central Africa, on the equator. It is the third largest country in Africa, two thirds the size of Western Europe.  It has vast natural resources and its forests are home to endangered species of Mountain Gorillas and elephants. However, the recent history of the DRC has been one of war and unrest. A former colony of Belgium, the country gained independence in 1960.  After a political coup, the Congo became known as Zaire under its dictator Joseph Mobutu from 1965-1997. From 1998-2003 the country was at war and over 3 million people were killed.  Free elections were held in 2006 and the country became known as the DRC.

Income, Life Expectancy and Disease

Joint replacements are seldom performed in DRC. Those who can afford it travel to other countries such as South Africa or India for surgery. The average income in this country is approximately $600 per year, which ranks it as one of the poorest countries in the world. Life expectancy is only 45 years as 20% of children die before age 5.  Malaria and other tropical diseases are extremely common as is tuberuclosis, polio, and HIV/AIDS. Most of the people we met were in their 60’s but a few were in their 80’s. Most were surprisingly very healthy, with high blood pressure and diabetes being the most common medical problems.  

The Patients We Evaluated

In a day and a half, the five of us met with the team of doctors and nurses we will be working with during our trip. Everyone worked incredibly hard. In this short time, we evaluated almost 90 patients.  Many people that we saw had very severe arthritis.  Many patients had much more severe deformities then we typically see in the US. Everyone was extremely grateful. Some patients waited over 10 hours to see us that day in 90 degree heat.  When I apologized to my last patient of the day for her long wait, she said simply “when you are in pain you will wait.”  

The people of the Congo have endured much hardship and poverty due to wars and political corruption. Access to good medical care is extremely limited.  We hope that we can make a positive difference in the lives of the people we care for during our return trip to the DRC in July to perform knee replacement surgeries.  More information on our upcoming trip can be found at

How to Lose Weight When Your Joints Hurt

Posted on April 26, 2016.

by: Kathleen A. Hogan, MD

People who are obese (body mass index -BMI >30) have an almost seven times increase in the incidence of knee arthritis compared to those with a normal body mass index (BMI 18.5-25). Weight loss has been shown to reduce the pain associated with knee arthritis and improve function.  However, many of my patients with severe knee or hip arthritis tell me that they are unable to lose weight because they cannot exercise due to their arthritis pain. How can you lose weight when you cannot exercise?  

This article is meant to give you some suggestions and ideas on how to lose weight when your joints hurt too much to exercise. You should talk with your medical doctor before starting a weight loss program, and about specific dietary or physical limitations you may have.

Keep a Food Diary

My first suggestion is to keep a food diary. There are many free apps that you can download to your phone or computer which determine the caloric content of what you eat. For some people, just keeping track of calories can prevent over eating. Some patients tell me they do not eat very much but still gain weight.

Sometimes it is not how much you are eating but what you are eating.  For example, 200 calories can be a plate overflowing with broccoli or carrots, half a hamburger, or half a candy bar.  Which is going to fill you up the most? Unfortunately the candy bar tastes the best!  Keep in mind that 200 extra calories take approximately an hour of walking to burn off!

Use Calorie Information to Make Healthier Choices

Many restaurants now list calories which can help you make healthier choices. The cafeteria at Catholic Medical Center lists “better alternatives” to high calorie foods. For example, who would have guessed that Baked Potato chips have less calories and fat (130 cal, 2g fat) then French Fries (300 cal, 15 g fat)? A bagel with cream cheese has over 400 calories compared to only 170 calories in a slice of french toast. Small changes in food choices can sometimes make a large difference in the number of calories consumed throughout the day.

Be Active Throughout the Day

Being active throughout the day is also important. This increases the number of calories you burn.  If you are very sedentary, you will need to consume considerably less calories each day to avoid gaining weight compared to someone who is more active.

Many patients with arthritis complain that their joints feel stiff when they get up from sitting.  Your joints are made to move. Movement lubricates all joints, even those with arthritis. Just because your knees hurt too much to run on the treadmill does not mean that you cannot exercise.

Do Low Impact Exercise

Swimming, water aerobics, biking, and the elliptical trainer all put less impact on your joints then walking. Strength training builds muscle and burns calories. It also builds bone density. The stronger your muscles are, the better they support your joints which reduces pain from arthritis. If you have never lifted weights before, you may want to start off by working with a sports trainer or physical therapist to learn how to do it correctly.

Barre, pilates, and yoga classes can also improve your flexibility, strength, and balance in addition to burning calories.  Some gyms and senior centers offer classes specifically designed for people who have arthritis.    Exercising with other people can help you stay motivated.  Even thirty minutes a day of exercise can have a positive effect.

Don’t Give Up

Do not give up. Just because you had a cupcake and sat on the couch tonight watching television does not mean you cannot exercise or lose weight. Try not to be too hard on yourself and set realistic goals so that you will achieve them.  Arthritis may make weight loss more challenging, but nothing is impossible. The first step is always the most difficult.

Do I Need a Joint Replacement?

Posted on March 24, 2016.

by: Kathleen A. Hogan, MD

As a specialist in joint replacement, I am frequently asked “How will I know when it is time to have my hip or knee replaced?”  As we age, most people experience intermittent pain in their joints, usually worse with activity.   Sometimes this pain is due to arthritis, but there are many other causes of joint pain. A few of these causes  include muscle pain, stress fractures, tendonitis, fibromyalgia, Lyme disease, and inflammatory conditions. Arthritis is caused by damage to the cartilage of a joint.   Pain from arthritis is  the result of the inflammation this cartilage damage generates.   Arthritic pain is often intermittent.  If you have arthritis it is likely that you will have good and bad days.  You may feel worse with changes in the weather.   X-rays may show loss of cartilage and development of bony deformities.   

Not all patients with hip and knee arthritis will need joint replacement surgery.  Some patients have x-rays which show they have terrible arthritis and yet they continue to be active.   Symptoms of pain and swelling can often be treated with anti-inflammatory medications and corticosteroid injections.   Improving muscle strength can help reduce stress on the joint.   Canes and walkers can be used to decrease the force of body weight on the joint.  Weight loss can be especially beneficial as you place forces of up to 5 times your body weight across your knee joint during stair climbing.

Most of my patients with arthritis want me to tell them if they are ready for a joint replacement.  My response is that you will tell me when you are ready for surgery.  Only you know if the discomfort and pain that you experience is bad enough to have a major surgery.   Does your knee or hip hurt you every day? Does your arthritis pain keep you from doing things that you enjoy? Keep in mind that joint replacement does not give you back the knee or hip you had when you were 20 years old.  This is an artificial joint made of metal and plastic.  It will feel better than your arthritic joint but different than a normal one! The majority of people who have their hip or knee replaced are happy with the results and feel that they “have been given their life back”.  

Joint replacement surgery is not without risks.  Although complications are rare, they can and do occur.   When your arthritis pain can no longer be improved with other treatments, the benefits of surgery – relief of pain, improvement in mobility, increased function – far outweigh the risks.  No one should feel they were “talked into” having joint replacement surgery by their surgeon or even by a family member.   Deciding to go forward with joint replacement surgery is a decision which will have a major impact on the rest of your life, and it needs to be your decision.
